Abstract

The invention relates to novel substituted bipiperidinyl derivatives, to processes for their preparation, to their use for the treatment and/or prevention of diseases and to their use for preparing medicaments for the treatment and/or prevention of diseases, in particular for the treatment and/or prevention of diabetic microangiopathies, diabetic ulcers on the extremities, in particular for promoting wound healing of diabetic foot ulcers, diabetic heart failure, diabetic coronary microvascular heart disorders, peripheral and cardial vascular disorders, thromboembolic disorders and ischaemias, peripheral circulatory disturbances, Raynaud's phenomenon, CREST syndrome, microcirculatory disturbances, intermittent claudication, and peripheral and autonomous neuropathies.

and
R 2 is selected from the group consisting of hydrogen and C 1 -C 4 -alkyl;
or
